Seeing Lan Yu looking at him with a puzzled expression, Mo Wuji laughed and said, "Brother Lan, you're selling your medicinal herbs to our pill refining workshop at a price even higher than near the battlefield. Why go further for what's near?"

The thought of penicillin as a product made Mo Wuji feel great. What better wound medicine could there be than penicillin, which prevents bacterial infections? Most importantly, he could produce penicillin using Dan Han Pill Refining's equipment.

Lan Yu looked at Mo Wuji with some suspicion. He had been dubious ever since Mo Wuji claimed to be a pill refiner from Dan Han Pill Refining.

"Pharmacist Mo, I've heard that Dan Han Pill Refining has been struggling lately..." Lan Yu's tone was euphemistic, but his meaning was clear: did Mo Wuji have the capability?

Before thinking about penicillin, Mo Wuji wouldn't have dared to boast so much. Now, he said without hesitation, "Brother Lan, you will soon see Dan Han Pill Refining shocking everyone in Chengyu Kingdom again, because a big merchant has directly invested millions of gold coins into Dan Han Pill Refining."

Lan Yu didn't delve into whether this was true or false. Even if it was false, he didn't care. At worst, he could just sell his herbs to someone else. "Alright, then I won't go further."

"Besides the usual herbs, I also need some special herbs. I'll write them down later and trouble you to find them for me. In two months, no matter how many herbs you have, you can bring them to Dan Han Pill Refining, and I'll give you a price that's 10% higher than the front lines," Mo Wuji said, picking up a notepad and pen from the table.

Penicillin production wouldn't require many medicinal herbs. Besides using the herbs for research, he also needed to create some ancillary products for Dan Han Pill Refining; he couldn't just sell penicillin alone. Of course, the main purpose was to continue refining his meridian-opening medicinal liquid.

Lan Yu frowned slightly. "Wait, two months is too long. I can't wait."

Mo Wuji chuckled. "Brother Lan, are you in a hurry for money? If you're not in a hurry, what's the rush? The war isn't ending anytime soon."

Lan Yu thought for a moment and realized that Mo Wuji was right. Although going to the border to trade would bring a slightly higher price, it would also be more dangerous. Two months was nothing.

"As you said, write down the herbs you need," Lan Yu said. He was a decisive person. Since he had agreed, he wouldn't hesitate. He sensed a strong confidence in Mo Wuji's words.

Mo Wuji knew that Lan Yu would agree. No one would go to the war-torn border unless they had no choice. After Lan Yu agreed, he wrote down dozens of herbs on the notepad and handed it to Lan Yu.

"Dragon Essence Grass, Hundred Flower Fruit, Ai Vine, Chicken Blood Vine, Dark Yellow Ginseng, Thousand-Year Pine Root, Fire Essence Stone..."

Lan Yu frowned as he looked at what Mo Wuji had written, because he had never heard of many of the herbs.

"Pharmacist Mo, maybe the herbs you've written down are too high-level, and I don't recognize many of them. For example, this Hundred Flower Fruit, Ai Vine, Night Needle Flower..." After reading it twice, Lan Yu reluctantly returned the notepad to Mo Wuji.

Mo Wuji instantly understood what was happening. The names must be different here than on Earth.

With that thought, he quickly took another notepad and started drawing pictures, while also explaining the growth characteristics of each herb. For example, Fire Essence Stones are usually found at the bottom of dried volcanic rocks, Ai Vines grow in damp places, and Night Needle Flowers bloom purple flowers at midnight...

"So the Hundred Flower Fruit you're talking about is the Color Fruit, and the Night Needle Flower is the Night Purple..." Lan Yu realized, and then looked at Mo Wuji with some confusion.

Mo Wuji was a pharmacist, so how could he mistake herbs? Could he be mistaken? But that wasn't right either. He had never heard anyone call the Color Fruit the Hundred Flower Fruit.

"Hehe, it's my fault. I learned ancient pill making from my mentor, and I forgot to change the names. I really can't name many of the current herbs. I need to buy a herb identification guide," Mo Wuji said without changing his expression.

So that was it. Lan Yu didn't suspect Mo Wuji. After all, Mo Wuji had written down the characteristics of the herbs with different names, and even drew pictures of them. It shouldn't be fake.

"Alright, I'll leave first. I'll come to Dan Han Pill Refining in two months," Lan Yu nodded, put away the notepad Mo Wuji had left behind, and bid farewell to Mo Wuji.

Mo Wuji breathed a sigh of relief and slowly walked out of the hotel. The market research for the day wasn't a complete waste.

He wasn't afraid of Lan Yu obtaining the medicinal liquid formula he was researching. Not only did he have several important herbs in his possession that he hadn't given to Lan Yu, but even if he gave Lan Yu all of them, no one else would be able to create that medicinal liquid.

...

As soon as Mo Wuji returned to Dan Han Pill Refining, Lu Jiujun rushed over urgently. "Brother Mo, when will you start researching new medicine? I have a few half-finished formulas here..."

Mo Wuji waved his hand. "I already have a new formula. Those half-finished ones don't matter. I want to see some of Dan Han Pill Refining's pill refining books. Also, I'm short on gold coins to buy some herbs for research."

"That's not a problem. I'll take you to Dan Han's herb library first," Lu Jiujun said without hesitation. He was just grasping at straws.

...

Although Dan Han Pill Refining had declined, it still had many herb books, many of which couldn't even be bought on the market.

As soon as Mo Wuji saw these pill refining books, he knew that he didn't need to buy any herb identification guides. He casually said to the attentive Lu Jiujun beside him, "Lao Lu, help me find a few reliable people. Once the new medicine is out, we'll produce it in the courtyard of our workshop. Remember, the medicine I'm refining must be kept secret, so the people must be reliable. We'll start in two days. In two months, it will be time for Dan Han Pill Refining to rise. No, it will shock the entire pill refining world."

Even though Lu Jiujun's Dan Han Pill Refining was dilapidated, it wasn't without its assets. The courtyard of this workshop was large enough.

In fact, Mo Wuji was very clear that no matter how much he tried to keep it secret, the method of collecting Penicillium and fermenting penicillin wouldn't remain secret for long, because it was too simple. The only thing that could be kept secret was the production of the nutrient solution. The nutrient solution was also too simple; once it was leaked, it would be imitated as well. But Mo Wuji didn't care. As long as he could earn his first pot of gold, he would have plenty of ways to make money. However, Mo Wuji believed that he wasn't lying at all when he said that penicillin would shock the entire pill refining world. This was originally a groundbreaking product.

These words were like a magic pill that instantly restored Lu Jiujun's vitality. He quickly patted his chest and said, "Brother Mo, don't worry. I guarantee that no one will leak any secrets of Dan Han Pill Refining."

"Wait..." Before Lu Jiujun could leave, Mo Wuji found paper and pen and wrote down a long list of various utensils, handing them to Lu Jiujun. "Also, buy these things to prepare for making the new medicine."

Lu Jiujun took the paper that Mo Wuji handed him with a puzzled expression, and asked, "What are you going to do with so many different kinds of glass bottles and test tubes?"

Mo Wuji waved his hand. "Don't worry about it here. Just listen to me. In two months, it will definitely bring Dan Han Pill Refining back to life."

These weren't for penicillin, but for his meridian-opening medicinal liquid.
